"vcodec == h264 ::" -> in every case of h264 encoded files."-vc coreavc," should work well, but it will try to use coreavc to every file, not just h264 ones, and that will slow down pms and maybe even stability problems. I know coreavc avc only decodes some codecs.

When -vc coreavc is defined in custom settings, then "," is mandatory because coreavc is used for all files, not h264 only so "," defines to use next codec in priority = encoding worksWhen -vc coreavc is defined in expert settings, it is possible to define codec for which it will be used so defining:

True.My testing found that some files with CoreAVC are encoder about 25% faster but for other I found that speed is same or sometimes worse. So it depends...not always using CoreAVC(Cuda) decoding is helpful but in most of cases yes.I will make another tests when Sherpya will do more stable and tested MEncoder builds with dsnative.dll library.Now experimental MEncoder build support DXVA HW decoding (ATI/Nvidia) but it doesn't work for now and I also suppose DXVA will not be usable for encoding part because decoded frames are passed to GPU directly and not to memory first so MEncoder can use them.

ExSport,Does the -mc 0.005 setting delay either the staring of the video or audio when the movie start? Or is it something else? e.g. if I have a movie that the audio is ahead of the video, would I increase this setting to -mc 0.01????

Number after -mc represents how many seconds MEncoder is allowed to repair bad sync on 1 frame of movie.When bigger number is used, sometimes it leads to unsynced audio on files which needs -mc 0 -noskip parameters.Because that I use so small nr. because it has same effect as bigger numbers but doesn't have side effect as described above.It has nothing to do with delayed start of video file.It is something like strenght indicator of syncing feature in MEnocder. But as I said more power leads sometimes to desync.Because that 0.005 is the best value for me.

Another quick question for you ExSport or oceanm, I have an mkv movie that when I play with mencoder the sync is just not right, I think the audio is just slightly ahead, But, when I play it with mencoder/avisynth the sync is spot on. Why is this, that is why I was asking about changing the 0.005 value, I thought I could change the sync from the start, as in delay either the video or the audio. Thanks.

Ok, just went to try to watch this movie again, and with oceanm sittings, avisynth/mencoder doesnt work, I know we are forcing mencoder-mt and coreavc to transcode, but is there a way we can skip like when using "," onto the next available option?
